Dogs can drink milk in small quantities, but many dogs are lactose intolerant, meaning they have difficulty digesting lactose, the sugar in milk. A few tablespoons of cow's milk or goat's milk occasionally can be safe for dogs that are not lactose intolerant. However, giving milk in larger amounts can cause digestive problems such as diarrhea, vomiting, and upset stomach. Milk is also high in fat and natural sugars, which can contribute to obesity and pancreatitis if consumed excessively. Puppies can digest their mother's milk well because they produce lactase enzymes, but many adult dogs produce less lactase and thus can develop lactose intolerance. It is important to introduce milk cautiously and consult a veterinarian before giving milk to dogs regularly or in larger amounts. In summary, milk can be an occasional treat for some dogs but should be avoided or limited for those sensitive to lactose or prone to digestive issues.
